2014-7-22  Basic Concept Prestressed concrete is basically concrete in which internal stresses of a suitable magnitude and distribution are introduced so that the stresses resulting from the external loads are counteracted to a desired degree. Pre-stress is introduced by stretching steel wire and anchoring them against concrete.

Prestressed Concrete: Types, Advantages Disadvantages

The reinforcement of concrete using excessive tensile steel improves the effectiveness of the material. The prestressing system works for a span greater than 35 m. Prestressing will increase the shear strength and exhaustion resistance of concrete. Dense concrete is provided by a prestressing system, thereby bettering durability.
